Application August 28,

1 Claim.

This invention is applicable to refrigerators of any size but is moreparticularly valuable to that class of regriferators of the larger sizesin which meat and other perishable goods are kept and which are providedwith refrigerating means to keep the meat and goods properly cooled.

An object of the invention is to prevent warm air pockets and to givethe cold air currents the most effective direction.

An object is to provide air baffle pans having a forward gutter with anadded pitch to speed up the water drain and being provided with a ledgeto direct down draft and to prevent ice forming in the gutter.

Simplicity and moderate cost are also objects of the invention.

Another object is to provide baffles of siphon type which will assureperfect air circulation and keep the refrigerator free from sweat andmoisture at all times.

Another object is to make provision for easily and conveniently cleaningthe refrigerator throughout, so as to secure perfect sanitation.

It is understood that changes may be made in 5 the air circulation andconstruction of parts without departing from the scope of the inventionor from the principles therein disclosed and claimed.

Other objects, advantages and features of invention may appear from theaccompanying 0 drawings, the subjoined detailed description and theappended claim.

The accompanying drawings illustrate the invention.

1933, Serial No. 687,082

The refrigerator body is constructed with walls a, b, c, and 01, top 6and floor f, enclosing a refrigerator chamber 1 and a storage andcooling room 2, and is provided in one end with the cooling and storageroom door 3. 4 indicates a window in one end and 5 a window in the side.The door 3 is appropriately hinged as at 6 and secured with anappropriate latch as at 7.

The walls are preferably constructed with outside and inside woodenpanels formed of tongued and grooved boards, preferably flooring nailedto upright studding, plates and sills forming chambers filled withinsulation g.

The refrigerating chamber 1 is arranged above the cooling room 2 and isseparated therefrom by the air bafiie pans 8 and 9 above which isprovided refrigerating pipes 10 for the purpose of lowering thetemperature of the cooling room.

The air baflie pans 8 and 9 comprise panels 11 and 12 that are fixed tothe transverse members 13 and 14 and form the chambers filled withinsulation 15.

16 indicates the wedge supports that are interposed between the panels12 and support members 1'? that hold the air bafiie pans in position asshown in Figs. 1, 2 and 3 of the drawings.

The air bafi'le pans slope downward toward a central vertical planewhich is indicated by the section line X2 in Fig. 1, and are providedwith a galvanized iron or suitable covering 18 which overhangs as at 18athe forward gutters 19 that are provided with an added pitch beginningat 20 at the front end and sloping downward toward the rear end as at 21as shown in Figs. 2 and 5 to speed up the water drain to prevent iceforming in the gutters.

The overhanging ledge 18a extends as far as possible over the gutter tostill permit the water to drop into same. The heavy cold air hits thevair baffle pan and the pitch of said pan gives the cold air a momentumwhich with the aid of the ledge 18a, causes it to slide over withoutentering the gutter to any great extent; and then goes down through thecold air space 22 between the gutters 19 into the cooling room below asshown in Fig. l of the drawings.

To permit the water to escape from the gutters l9, outlets 23 areprovided that empty into the drain gutter 24 that is fixed to one of thesupport members 17 at the rear end which is provided with a dischargeoutlet pipe 25 that empties into the drain pipe 26 that leads throughthe rear refrigerator Wall c into a sewer or other suitable drain, notshown.

Baiiles 27 of which there are two in number are shown mounted upon thehighest edge of the air baiile pans 8 and 9 and extend from the frontend to the rear end of the refrigerator and fixed thereto and held inalignment by the strips 28.

The said bafiles 27 comprise slats 29 that are arranged and spaced at anangle to form the openings 30 that permits the warm air to passtherethrough.

31 indicates the top strip and 32 the bottom strip and at 33 is shown afinishing strip which are all fixed to the baffle in a manner well knownto the art.

The baflles 27 are spaced a certain distance away from the side walls dand g to form flues 33 that permits the warm air to rise from thecooling room 2 below.

I have thus provided means for collecting and discharging the drip waterfrom the refrigerating chamber and have made provision for keeping thecooling room practically dry.

The air circulation is as follows: When the warm gases reach the ceilingof a refrigerator generally they will condense and leave the ceilingwet. The warm gases are drawn through the baffles 27 before they reachthe top, are cooled by the refrigerating pipes 10 and become heavy anddrop through the cold air space 22 into the cooling chamber 2 below.

As the cold air passes downward the warm air is drawn thru the baffles27 to replace the cold air on its downward course.

Provisions stored within the cooling room 2 as well as thermal radiationfrom the refrigerator body cause a gradual rise in the cooling roomtemperature and the warmer air will gradually rise along the walls 01and b of the refrigerator until said warmed air passes through the ilues3S, and through the openings 30 of the baffles into the refrigeratingchamber 1 as shown by the arrows in Fig. 1.

I claim:

In a refrigerator provided with insulated walls, top and bottom, andhaving a cooling room and a refrigerating chamber thereabove; insulatedair baffle pans having a downward slope and separating said cooling roomfrom the refrigerating room; means to support said air baffle pans;gutters fixed to the forward end of said air bafile pans and providedwith an added pitch to speed up the water drain; a ledge extendingpartly over said gutters to direct down draft and to prevent ice formingin said gutters; said gutters being provided at one end with outletsthat permits the water to drain through; a drain gutter directlyunderneath said outlets and means to drain water from said drain gutterto the outside of the refrigorator.
